Question

Answer 1

`A = ( 3 + 1/2 - 2/3) - ( 2 - 2/3 + 5/2) - ( 5 - 5/2 + 4/3)`

`A = 3 + 1/2 - 2/3 - 2 + 2/3 - 5/2 - 5 + 5/2 - 4/3`

`A = ( 3 - 2 - 5) + (-2/3 + 2/3) + ( -5/2 + 5/2)  + ( 1/2 - 4/3)`

`A = -4 + 0 + 0 + ( 3/6 - 8/6)`

`A = -4 +0+0 + (-5)/6`

`A  = (-29)/6`

 

 

`A = ( 3 + 1/2 - 2/3) - ( 2 - 2/3 + 5/2) - ( 5 - 5/2 + 4/3)`

`A = ( 18/6 + 3/6 - 4/6) - ( 12/6 - 4/6 + 15/6) - ( 30/6 - 15/6 + 8/6)`

`A = 17/6 - 23/6 - 23/6`

`A = (17-23-23)/6`

`A=-29/6`

Answer 2

`C1`
`A=(3+1/2-2/3)-(2-2/3+5/2)-(5-5/3+4/3)`
`=3+1/2-2/3-2+2/3-5/2-5+5/3-4/3`
`=(3-2-5)+(1/2-5/2)+(2/3-2/3+5/3-4/3)`
`=-4-2+1/3`
`=-17/3`
`C2:`
`A=(3+1/2-2/3)-(2-2/3+5/2)-(5-5/3+4/3)`
`=17/6-23/6-14/3`
`=-17/3`

Answer 3

`A = ( 3 + 1/2 - 2/3) - ( 2 - 2/3 + 5/2) - ( 5 - 5/2 + 4/3)`

`A = 3 + 1/2 - 2/3 - 2 + 2/3 - 5/2 - 5 + 5/2 - 4/3`

`A = ( 3 - 2 - 5) + (-2/3 + 2/3) + ( -5/2 + 5/2)  + ( 1/2 - 4/3)`

`A = -4 + 0 + 0 + ( 3/6 - 8/6)`

`A = -4 +0+0 + (-5)/6`

`A  = (-29)/6`
